12 Claims.

This invention relates to punching machines and more particularly to the type which enables selective reproduction of data on one card transposed from and under control of another card when the latter bears predetermined classification data.

It is obvious that reproduction of cards having certain classifications may be performed by manually sorting or machine sorting promiscuously arranged cards to sort out those having selected classifications and then reproducing them, but after such cards have been reproduced it is necessary to replace the selected cards back in the file, if the file is to remain intact.

This procedure is laborious and entails considerable handling of all cards in the file, with consequent possibility of misplacing cards.

It is, therefore, a broad object of the present invention to provide an improved means to select from a file of promiscuously arranged punched cards those having classification data corresponding to a setup in the machine and upon location thereof utilize such punched cards to transpose certain data thereon to another card.

A still further object of the invention is to enable the searching of selective classification data when it consists of all numerical data, all alphabetic data, or a mixture of both.

Another important feature of the invention is to provide for the selective reproduction of an alphabetically designated card dependent upon the location of searched-for zone classification data, and interrelated numeric data. This feature relates primarily to the search for alphabetic classification data where the latter is represented by combinations of zoning perforations at R, X, and one in the same column at 9l index point positions.

Another specific object of the invention relates to the provision of improved means to suppress the feeding of blank cards until a punched card is found which corresponds to the selected classification data set up in the machine, and then under control of comparing means cause the concomitant feeding of a blank card past the punching mechanism as data to be transposed from the punched card is analyzed by supplemental analyzing means.

Another object of the invention relates to an improved means of construction of classification data setup means, consisting of an emitter which transmits data representing impulses. By convenient plug connections to the emitter selected impulses may be derived which correspond to the classification data searched for. Such emitter also provides for the transmission of zoning impulses and numeric impulses which are selected in combination according to the searched-for letter of the alphabet.

Other objects of the invention will be pointed out in the following description and claims and illustrated in the accompanying drawings, which disclose, by way of example, the principle of the invention and the best m0de,'which has been contemplated, of applying that principle.

Fig. 6 is a timing diagram.

In Fig. 1 there is shown a part of the essential elements of the card reproducing machine disclosed in Patent No. 2,032,805 or the corresponding Reissue Patent No. 21,133 and in briefly describing the operation of the mechanism and changes in the patented machine to carry out the present mode of operation, the same reference characters as far as is possible Will be employed as are used in the patent to facilitate ready reference thereto for any further detailed explanation.

Referring to Fig. 1, in the magazine R are a I placed a series of promiscuously arranged punched pattern cards In, from which file certain cards are to be reproduced.

Arm 5! is oscillated to cause the reciprocation of a slide 53, said slide carrying a picker 5!! for advancing the lowermost card to a pair of feed rollers 59, which convey the card to a sensing or analyzing station comprising brushes [5 and contact roller 262, from which station the card passes to feed rollers 65, 66 and from there to a second sensing station comprising brushes l6 and contact roller RI and here the card is conveyed by rollers 88, 91 and eject roller I02 to a discharge hopper I2.

In the magazine P of the punching section of the machine cards II which are blank in the columns to be punched are placed which are to be selectively punched under control of the selected pattern cards in the magazine R. From the magazine P the cards are fed singly by means of an arm 83, slide 84 and picker knife 85 to feed the lowermost card to rollers I03, I04, which convey the card to and past the punching station comprising a row of punches I8 and a die I61. From the punching station the card is conveyed by rollers I05, I06, I3I, I32 and eject roller I45 to a discharge hopper I3. The sets of rollers which convey the blank card through the punching section of a machine are intermittently driven as explained in the aforementioned Patent No. 2,032,805, so that the card is advanced in steps with each row of index point positions, causing momentarily a stop at the punching positions to receive the perforations if, at such time, the PM magnets are energized.

Energization of magnet PM will rock its armature structure I90, drawing a link I92 toward the right to effect coupling between an interposer I86 and plate I84. The plate I84 is carried by the member I11, pivoted at I83 and oscillated by means of a link I18 connected to an arm I16 on the shaft I15.

Further detailed explanation of the construction and operation of the card feed and punch mechanism may be had by reference to Patent No. 2,032,805 and it will be sufficient for the purposes of the present invention to now explain that when a card I previously found to contain perforations representing a classification set up in the machine passes brushes I6, circuits are completed through the perforations in the pattern card to energize the punch magnets PM, which magnets will couple the related punches to the oscillating plate I84 and effect punching in the corresponding index point positions of the blank card fed from the magazine P. After the pattern card and the blank card have concurrently passed their respective sensing and punching stations, the punched card is then fed by the rollers I05, I06, I3I, I32, eject roller I45 to the hopper I3. The brushes I5 determine whether a pattern card represents the classification data set up in the machine as will appear clearer in the description of the machine involving the circuit diagram. However, before going to the description of the circuit diagram, certain mechanical changes are made in the present clutch drive and will now be described.

In the Patent No. 2,032,805 feeding rollers 65, 66, contact roller 28I, feeding rollers 88, 91 and eject roller I02 are driven under control of the punch clutch engaged when the PCM clutch magnet is energized. In the present machine the operation of the aforementioned elements is removed from under control of the PCM clutch magnet and is placed under control of the RCM clutch magnets. The changes necessary to accomplish this are shown in Figs. 2 and 3.

In Fig. 2, reference numeral 31 designates a clutch driving gear 31 on shaft 38. The manner in which such gear is driven when the RCM clutch magnet is energized is fully described in Patent No. 2,032,805. When such clutch is engaged the card feeding mechanism associated with the R magazine (Fig. 1) is operated to feed a card and to also drive feeding rollers 59, 60 and contact roller 262 by gear connections fully described in the aforementioned patent. The manner in which the remaining feeding rollers 65, 66, 88, 91, I02 and contact roller 28I of the reading section are operated will now be described, it being noted that the feeding rollers 59 and 60 are driven by a ear 6| (Fig. 2) secured to shaft 38. Gear 6| meshes with a gear 62 on the roller 59. A smaller gear 63 on roller 59 cooperates with a similar gear 64 on roller 60 so that both rollers are turned simultaneously but oppositely. Gear 63 on roller 59 meshes with an idler gear 61 which in turn meshes with a gear 68 on contact roller 262. From said gear 68, gear connections are now provided to drive the feeding rollers 65, 66, common contact roller 28I, feed rollers 88, 91 and the eject roller I02.

The drive gear designated 92 in Patent No. 2,032,805 (see Fig. 2) has been removed and an idler gear designated 68a. (Fig. 2) is provided herein and is pivoted on a stud so that it meshes with the contact roll drive gear 68. Said idler gear 68a also meshes with gear 93 attached to the feed roller 65. Gear 93 on the feed roller shaft 65 also meshes with a similar gear 94 on the feed roller shaft 66. So far described, it is obvious that feed rollers 65 and 66 are driven by the RCM clutch of the reading section.

Also herein as in Patent No. 2,032,805, gear 18, driven by the PCM clutch, meshes with gear 86 and the latter meshes with a gear 81 (see Figs.

. 2 and 3). However, in Patent No. 2,032,805, gear 81 is secured to an extension of the feed roller drive shaft 88, but herein gear 81 is secured to a short jack shaft 81a (Fig. 3), axially aligned with the feed roller drive shaft 88. In other words, feed roller drive shaft 88 does not now extend sufficiently to carry the gear 81 and also the gear 89 but is broken at the point indicated by the legend in Fig. 3 as Shaft 88 out here." However, on stud shaft 81a the gear 89 is attached which meshes with a gear 90 attached to a shaft 9| which carries the cams for operating the cam contacts Pl-P6. Thus, the latter are driven when the PCM clutch is engaged, the same as in Patent No. 2,032,805. The severing of feed roller shaft 88 at the place indicated now disconnects the feeding of the rollers 65, 66, 88, 91, contact roller 28I and eject roller I02 by the PCM clutch and enables such elements to be driven by the RCM clutch magnet. To effect this, gear 93 which, it will be recalled, is driven when the RCM clutch is engaged, meshes with an idler gear 98 and the latter meshes with a gear 99 secured to the shaft of the contact roller 28I. The gear 99 meshes with an extra idle gear 99a provided in the present machine and which meshes with gear 95, carried by the feed roller 88. Gear 95 on roller 88 drives a similar gear 96 on associated roller 91. Another idler gear I00 meshes with gear 95 and serves to drive pinion IOI, mounted on card eject roller I02. Summarizing, such changes in the driving connections of the patented machine enables all of the feeding rollers and contact rollers of the reading unit shown at the left of Fig. 1 to be driven whenever the RCM clutch is engaged.

Operation of machine n connection with wiring diagram Prior to starting the operation of the machine, punched pattern cards of the file from which cards having certain classifications are to be reproduced are inserted in the reading unit magazine R. Like the machine disclosed in Patent No. 2,032,805, the magazine of the reading unit is provided with a card lever shown in Figs. 1 and 4a and designated RMCL and closure of the related contacts will close a circuit from the line 200 through such contacts, R6 relay to line 20 I. Also prior to the operation of the machine blank cards are placed in the magazine of the punching unit and the related card lever PMCL (Figs. 1 and 4a) is operated to close its related contacts to energize the R3 relay by an obvious circuit.

Thus, prior to the depression of the start key ST, the RGa and R3a relay contacts (Fig, 4a) are transferred. Depression of the start key ST causes the first card in the reading unit magazine R to be fed just to the comparing brushes I5 while the first card in the punching unit feed magazine P is fed just to the punching die I61. The depression of the start key ST closes a circuit from the line 200, start ke contacts, RGa contacts now transferred, R3a contacts now transferred, RID relay coil to line 20I. The latter closes its contacts RIM and the latter remain closed as long as the start key is maintained depressed. Under control of the RIM contacts a motor control circuit will be closed from the line 200, RIOa relay contacts, HD#I relay coil to line 20 I. The latter closes the HD# Ia contacts, thereby connecting the supply line to the main drive motor M. Motor M now being operated drives all of the unclutched mechanism of the machine as well as the shaft which close the C cam contacts.

Also upon closure of the RIM contacts, the R9 motor relay is energized by a circuit from line 200, RIOa relay contacts now closed, RI3b contacts now closed, R9 relay, to line 20I. A holding circuit for the R9 motor relay extends back through the R911 relay contacts, R9b relay contacts, Rl0a relay contacts, to line 200. An alternative holding circuit extends through the R9a contacts, C3 cam contacts back to line 200. It will be observed that the R911 relay contacts cannot be picked up unless the RI3b relay contacts are closed. Referring to Fig. 4b, C4 cam contacts are timed to close the energizing circuit for the RI3 relay between 9.6 at the end of the cycle and to 11.5 at the beginning of the next cycle. The opening of the Rl3b contacts prevents a pickup circuit for the R9 relay during this time. The starting circuit for the R9 motor control relay is held through R9a relay contacts and cam contacts C3 after the start key is released.

With R90 relay contacts and RIOb relay contacts now closed, the circuit for the PCM clutch magnet is closed from the line 200, relay contacts R90, RIOb, relay contacts RIa, normally closed. cam contacts CI, PCM clutch magnets to line 20I. The clutch magnet will be energized when cam contacts CI close at the end of the cycle and through the clutch connection thus made the picker 85 will feed the lowermost blank card out of the P magazine and just to the punches I8 and die I61 at the punching station. During this first card cycle the blank card operates the die card lever DCL (Figs. 1 and 4a) and closes related contacts to energize the RI relay by an obvious circuit and thus transfer RIa and RIc contacts. A circuit to energize the RCM clutch magnets is closed from the line 200 through R9c relay contacts, RI 0b relay contacts, R4a contacts now normal, SI switch, RI4b contacts now normal, S2 switch, C2 cam contacts, RCM clutch magnets to line 20I. Thus, the related clutch is now engaged so that picker 58 will feed the lowermost card from the R magazine to the comparing sensing brushes I 5. During this feeding cycle the seam N36? card just fed operates card lever RCL#I (Figs. 1 and 4a) to close the associated contacts and by an obvious circuit energizes the R4 relay to transfer the R4a, R40 contacts. Th energization of relays RI and R4 will then condition circuits so that subsequent cards may be automatically fed from the respective magazines but during the first card feeding cycle the following circuits occur to prevent the energization of the PCM clutch magnet during the following or second card feed cycle, initiated automatically as will be subsequently described.

It will also be noted that the energization of the RI and R4 relays transfer their respective contacts RIa and R4a so that the energizing cir cuit for the PCM clutch magnets now extends from line 200 through R90 contacts now closed, Rlflb contacts now closed, R4a contacts now transferred to a wire 204, the remainder of this alternative energizing circuit for PCM clutch magnets extending through R9'Ib contacts now open as will be presently explained, through CI cam contacts, PCM magnets, to line I. At this time of the cycle it should be observed that the transfer of the RIa contacts opens the previously described energizing circuit for PCM clutch magnets which is effective during the first card feed cycle. The opening of relay contacts R912) prevents the completion of the circuit when cam contacts CI close just prior to the second cycle.

In Fig. 4b Em represents an emitter driven synchronously with the C cam contacts (and also R and P cam contacts) and therefore its brush may be operated by the same continuously driven shaft of the patented machine, and Fi 2 herein. Emitter Em is timed to transmit impulses synchronously with the feeding of the pattern card past the comparing brushes I5. It

, will be recalled that in this machine the perforations are sensed in the order R, X, 0, 19 and correspondingly emitter Em is timed to transmit impulses in this order (see Fig. 6). Digit representing impulses may be selected b making plug connections from the plug hub 205 of the emitter to plug hubs 206 connected to comparing relays R51, R59, RBI and R63. Assuming that cards are to be reproduced only when pattern cards are found punched to represent the classification number 3578, plug connections (not shown for this example) will be made from the four plug hubs 206 to the plug hub 205 having the corresponding numeral designations. Therefore, during the first cycle of the machine initiated by depression of the start key, a circuit will be closed from line 200 through circuit breaker contacts CII (Fig. 4b), S3 switch now closed, RI cam contacts (driven by shaft 38) (Fig. 2) closed during the time that all of the digit impulses are transmitted by the Em emitter, through the R312 relay contacts now closed, (RIb contacts now being open), to the common conducting strip of the emitter Em, through the brush thereof, the related contact points, plug hubs 205, plug connections (not shown) to the plug hubs 206, to the R51, R59, R6I, R63 relays to line 200. Hence, the 3, 5, 7 and 8 impulses successively energize the relays in the named order, energizing the pickup windings thereof. Each pickup coil when energized closes its a holding contacts, energizing the H holding winding of each by a circuit from line 20 I, through the respective holding winding, its related a holding contacts, wire 20'! through the holding cam contacts C9 to line 200. It will be observed that the energized relays are held energized until 9.6 of the cycle.

Each relay R51, R59, RBI and R63 transfers its respective b comparing contacts which are cross-connected with the b comparing contacts of comparing relays R58, R60, R62 and R64. It is explained at this time that the last mentioned group of relays are selectively energized under control of the perforations in the pattern card when sensed by the brushes I5. Since, during the first card cycle the card has not been fed sufficiently past the brushes I5 and card lever contacts, relays R58-R64 remain deenergized and therefore the b comparing contacts are in the position shown in Fig. 4b. When the emitter transmits the 3 digit representing impulse at 3.3 in the cycle, at this time cam contacts Clo close to transmit an impulse from the line 200 through such contacts, wire 208, thence through the R5Ib contacts now transferred, R5817 contacts now normal and through a plug connection 209 to the pickup winding of the R91 relay to line 20L Each comparing order is also effective to energize the R91 relay by reason of the shunt connections 2 I so that similar energizing circuits for the R59, RSI, R63 relays may be effective at 5.3, 7.3 and 8.3 points in the cycle to repeatedly energize the R91 relay through the R59b, R6Ib and R631: contacts and the associated "17 contacts of the unenergized R60, R62 and R64 relays. However, the first impulse transmitted to the R91 relay is effective and the pickup winding thereof closes the related holding contacts R9'Ia and a circuit is then closed from the line 20I through the holding winding of R91 relay, R9'Ia contacts, R4 cam contacts and wire 2 to the line 200. It will be observed from the timing shown in Fig. 6 that the R4 cam contacts hold the R91 relay energized until the remainder of the cycle and during the first portion of the next cycle, during which time the CI cam contacts close. With the R912) relay contacts (Fig. 4a) now open and held open during the time-that the Cl cam contacts are closed, it will be seen that the alternative energizing circuit for PCM magnets from the wire 204 through the RS'Ib relay contacts, CI cam contacts to PCM clutch magnets is now opened at RB'Ib and, therefore, the clutch of the punch unit is not engaged, and the first card fed from the P magazine remains in position just before the die I61, and such blank card will be fed only past the punches I8 whenever a pattern card is found to represent the selected classification data.

The second card feed cycle is initiated automatically, as will be obvious from the subsequent description of circuits which keep the RID relay energized. The energizing circuit for energizing the ROM clutch magnets for the second card feed cycle extends from line 200 through R90 relay contacts now closed, RIIlb relay contacts now closed, Rla relay contacts now transferred, thence cthrough the Rl4b relay contacts now closed","S2 switch, C2 cam contacts, RCM clutch magnets to line 20L Thus, the clutch of the reading unit is now engaged and the card which was fed just to the comparing brushes I is now fed past such brushes for the analyzing of the perforations representing the classification data on such card. If the classification data is found to agree with the setup on the emitter Em then both the clutches of the reading unit and the punching unit are engaged and the first blank card is fed past the punches and die in synchronlsm with the feeding of the punched card past the reproducing control brushes I6. However, it is explained that after the manual initiation of the first card feed cycle, the machine will run automatically until cards in either magazin are exhausted or the stop key is depressed. This is accomplished by keeping the RH] relay energized by the following described circuits:

When the RID relay is energized by the start key depression, a holding circuit therefor is provided through RIOc contacts, R24a relay contacts, P6 cam contacts, back to line 200. Relay contacts R24a are closed by R24 relay energized under control of the R2 cam contacts. From Fig. 6 it will be observed that cam contacts R2 close to energize the R24 relay to close the R240. relay contacts just prior to the closure of the P6 cam contacts so that the hold circuit for RIO relay is closed when the P6 cam contacts close at 13.4 at the end of the cycle. The holding circuit remains closed for the end of this cycle and up to 9.4 of the next cycle when cam contacts R2 open. From 9.4 to 13.4 of this next cycle the holding circuit is open and if in the meantime a shunt circuit is closed, RI 0 relay remains energized to start the next machine cycle. This shunt circuit is a supplemental holding circuit for the RID relay and extends through the RIM relay contacts, punch magazine card lever relay contacts R3d now transferred, die card lever relay contacts RI 0 now transferred, switch S1 now in the position shown, reading magazine card lever relay contacts R62) now transferred, RCL#I card lever relay contacts R40 now transferred, stacker stop switches S6, S5, stop key contacts, back to line 290. If this shunt holding circuit is not completed between 9.4 to 13.4 of a cycle the start relay RIO will deenergize, the clutches R and P will latch up to disengaged position and the machine will coast to a stop between 6 and 9 under control of the C3 cam contacts. When cards are fed to operate RCL#I and DCL, the above shunt circuit is closed between l--8 before P6 and R241: contacts open at 9.5 and 9.4 respectively, to keep RIB relay energized to effect the next cycle of operation automatically.

When the machine operates automatically for the next cycle, cam contacts C2 will close at the beginning of the cycle to transmit an impulse to the ROM clutch magnets to then feed the next pattern card from the R magazine and concurrently feed the pattern card which was previously fed just to the analyzing brushes I5, past said analyzing brushes to search the perforated columns representing the classification data to determine whether it agrees with the emitter set up. According to the result of the comparing operation the machine may effect either of two operations; 1) when agreement is found the blank card fed just to the die I6! is fed past the card punches I8 concurrently with the feeding of the pattern card past the reproducing control brushes I6, or (2-) when disagreement is found the feeding of a blank card is suppressed and the next pattern card is fed past brushes I5 to determine whether it represents the classification data searched for. It will be assumed that condition (1) occurs whereupon the following operation takes place.

Preparatory to feeding the pattern card to the analyzing brushes I5, RCL#2, card lever is operated to close the related contacts (see Figs. 1 and 4b). As the pattern card passes the comparing brushes l5 circuits are closed through the perforations to the comparing relays R58, R60,

r. cu: IlIlIb d ,PWNCHING R62, R64, one of such representative circuits being traced as follows: Line 200, circuit breaker contacts CI I, switch S3, RI cam contacts closed during the analysis of the card, RCL#2 card lever relay contacts, brushes I5, and related plug connection to the pickup winding of associated comparing relays R58, 60, 62, 64, to line I. If the pattern card is perforated to represent 35, 78, impulses are transmitted to the aforesaid relays at diiferential times. Holding circuits for such relays are provided by the a contacts and cam contacts C9, as before. Also synchronously with the analysis of the pattern card emitter Em is transmitting impulses at the same differential times to the other comparing relays R51, 59. 6|. 63 by the aforementioned circuits. Where there is an agreement in numerical value in each order, paired comparing relays R51, R58; R59, R60: RBI, R62; R63. R64 are concurrently energized and the concurrent transfer of their related b comparing contacts prevents an impulse from being transmitted to R9! relay. The R9Ib contacts of the latter remain closed and when CI contacts close, an impulse is transmitted to PCM clutch magnets, and when C2 cam contacts close an impulse is transmitted to RCM clutch magnets. The machine now operates for the next cycle to feed a blank card past the punches I8 concurrently with the analysis of card perforations in the pattern card as it passes the reproducing control brushes I6. Brushes I6 may be correlated with the same card columns representing the searched numerical classification to thereby transpose such values to the blank card. or other columns of data may be analyzed by brushes I6 and transposed to the blank card. In

either instance the punch magnet operating circuits are under control of brushes I6 described as follows: Just prior to entering the reading station comprising brushes I6, CCL card lever operates to close its related contacts (see Figs. 1 and 4b). The circuit extends from line 200, through circuit breaker CII, PI cam contacts closed during the analysis of the card perforations, CCL card lever contacts now closed, brushes I6, and respective plug connections to the PM punch magnets connected to line 2III. Of course, following cards are fed from the magazines R and P, and the punched pattern card following the one analyzed by brushes I6 will be analyzed by brushes I5 to determine if it represents the searched-for numerical classification.

If condition 2 occurs then R91 relay is energized and contacts R91?) open to prevent PCM clutch magnets from energizing. However, clutch magnets RCM energize to feed a following card past the brushes I5 to search for its numerical classification, and at the same time the card not having the desired numerical classification is fed past brushes I6. Since PI contacts are not closed the analysis of the perforations by brushes I6 is ineffective and punch magnets PM are not energized. It is explained that due to the change in construction herein whereby feeding rollers 65, 66, contact roller 28I, feeding rollers 88, 91, eject roller I02 is driven by the ROM clutch such undesired pattern card is fed to the hopper I2.

Thus the machine operates automatically until either one or the other of the magazines R, P is empty, whereupon the machine will stop. Circuits for effecting this are well known and briefly when the P magazine is empty, R3d contacts transfer to normal to break the holding circuit for the RID relay. The punch unit cannot be Search Room restarted unless the P magazine is refilled because the start circuit to energize RIO relay by depressing the start key will be open at normally open R3a rela contacts.

When the reproducer magazine R becomes empty the machine will stop because R6b contacts transfer to normal to deenergize the RI 0 relay. However, the machine may be restarted for one cycle by depressing the start key although the R magazine is not replenished, In this case RCLitI contacts are closed to energize R4 relay and Rid contacts are transferred, The start circuit is now from the start key ST, R6a normally closed contacts, Rdd contacts now transferred, R3a contacts now transferred, to RIIJ relay. During this card feed cycle the last card on the reading side will advance past brushes l5 to brushes I6. Since the card leaves RCL#I card lever contacts R40 are now open to break the holding circuit of the RID relay, and the machine will now stop. Also R4d contacts come to normal. The start circuit is now closed upon depression of the ST key, the circuit extending through the normally closed contacts RBa, RM, RM to the RIO relay. The previous analysis of the pattern card by brushes I5 will determine Whether such agrees with the numerical setup and if found to agree will cause the last blank card to be fed past the card punching mechanism in synchronism with the feeding of the last pattern card past the brushes I6. If agreement is found the circuit to energize the PCM clutch magnets is from line 200, R relay contacts, RIIlb relay contacts, Rla relay contacts normally closed, RIc relay contacts now closed, R30 relay contacts, wire 204, R911) relay contacts, CI cam contacts, PCM clutch magnets, to line 20L If both feed magazines become empty at the same time, the machine will stop and it will be necessary to insert in the P magazine one blank card, if the machine is to be cleared of cards; otherwise both magazines are replenished with cards.

Selective card punching determined by pattern cards having alphabetical classification data with or without numerical classification data Another feature of the machine consists in providing for selective card punching when the classification data on pattern cards represents alphabetical data with or without numerical classification data. For example, pattern cards representing A389, taken in the following as an example, can be selected from classifications such as ABAB, 1212, DZHK, DB12, etc.

The alphabetical code may be any suitable one, and preferably consists of the code used to represent alphabetical data by the Hollerith type of card bearing twelve index point positions 9-1, 0, X and R, such code being identified in Patent No. 2,315,741. In such code A is represented by a combination of holes at R and I, and B by holes at R and 2.

When comparing data represented by two successively analyzed holes in a card column the Em emitter is plugged to emit such impulses to a single comparing relay R51, 59, BI, 63. To prevent possible back circuits when searching for combinational holes in a column a selector relay IOI and associated contacts a, b, are used for each column that combinational holes are searched for. Relay IIII is energized by an obvious circuit under control of the R5 cam contacts which closes during the analysis of the zoning holes R, X, 0 (see Fig. 6) and closes its a multiple contacts. During the analysis of the numeric holes 1-9 in the named order, the b contacts are at normal and closed. Since search is made in the above example for the zone hole R in two card columns, plug connections2l2, 2|3 are made from R impulse plug socket 295 to R, X, plug sockets of the selector. Also since a search is made for digit impulses 1 and 2, plug connections 2, M5 are made from digit representing plug hubs 205 of the emitter to the 1-9 plug sockets of the selector. The plug connections 2H5, 211 are made to the respective R51, R59 comparing relays. Plug connections 2I8, 219 are made between the 8 and 9 plug hubs 205 to plug hubs 296 of the RBI, R63 relays, in order to search for the 8, 9 numerical data.

While brushes are searching the two left hand card columns for R, X, 0 perforations, cam contacts R5 are closed to close the 11" contacts of the selector and upon presence of such R per- [oration in the assumed example impulses are transmitted to the R58, R60 comparing relays. Concurrently, the Em emitter transmits an impulse when R point is contacted, the impulse being directed through the a closed contacts to the paired relays R51, R59. The holding circuits for the comparing relays extends through related a contacts and cam contacts C8 closed during R, X, 0 time. (See Fig. 6.) Thus, if there is an agreement in the zoning perforations, R91 re lay remains unenergized. Thereafter, the Em emitter transmits through the 12" contacts of the selector 1 and 2 digit impulses to the R51, R59, relays at the time paired relays R58, R60 are energized by the same impulses under control of brushes I5. If there is an agreement in numeric data R91 relay still remains unenergized. Of course, non-simultaneous impulses, either zoning or numeric, cause one or the other of the paired relays to be energized, and through the comparing circuit cause R91 relay to be energized.

Summarizing, selective punching is dependent upon agreement in the two zones, since dissimi larity in either zone causes R91 relay to be energized and selective punching suppressed.

The above example merely takes two alphabetic characters A, B, as an example, and for other characters X, 0, index points may be the searched-for zoning holes and plug connections are made from corresponding plug hubs 205. All the compared columns may consist of alphabetic data, the IOI selector relay having the desired number of contacts to prevent back circuits.

Such back circuits may be explained by stating that without a selector and direct plug connections from Em to the comparing relays, the 1 digit impulse transmitted by Em would be directed to R51, back to R plug hub 205, and from such plug hub to R59 relay, improperly energizing the latter.

The size and number of data groups that are utilized are dependent upon the number of comparing relays. If another data group is used for control, similar comp ring relays and comparing network are provided to selectively energize R98 relay, and since its 1) contacts (Fig. 4a) have a similar control, selective reproduction may be dependent upon finding another searched-for classiflcation. Plug connections may be made as shown so that R911) and R98b contacts are in shunt so that agreement of only one data group will efiect selective card punching and disagreement of both data groups prevents card punching. Obviously, changing plug connections to place contacts R911) and R981: in series will enable selective card reproduction only when both classification data groups agree with the respective numerical setup, and disagreement of only one group of classification data prevents card reproduction.

Each data group may consist of all alphabetic data, all numeric data, or intermixed. All of the above variations follow from the present disclosure and show the wide variety of uses of the present machine.
